YMMV: Infinite Jest
- Harsher in Hindsight: The depiction of mental illness, depression and suicide, since Wallace erased his own map.
- Hilarious in Hindsight: That part about Orin getting onto to Boston University's football team? One year after the novel was published, the university disbanded its football team.
- Nightmare Fuel: In the first scene, the main character hears himself communicating completely calmly and rationally with those around him. Those around him hear him screaming in horrific pain, convulsing like he's absolutely lost his mind, to the point where they call an ambulance. And, Orin and the cockroaches.
- After the lengthy description of Randy Lenz's nightly walks, Wallace makes absolutely sure to add the detail that there are no locks on any of the doors in Ennet House.
- James Incandenza's death by putting his head in a microwave oven. Worse, it's Hal - at thirteen - who finds him.
- Limbic system lobotomies.
